为什么会出现以下错误：NameError：未定义名称'models'

Question

Whenever I run the program, I get the following error:

NameError at /table/
name 'models' is not defined

It says that there's an error on line 4 in my views.

Here is my views.py:

from django.shortcuts import render

def display(request):
    return render(request, 'template.tmpl', {'obj': models.Book.objects.all()})

Here is my models.py:

from django.db import models

class Book(models.Model):
    author = models.CharField(max_length = 20)
    title = models.CharField(max_length = 40)
    publication_year = models.IntegerField()

Here is my urls.py:

from django.conf.urls import url
from . import views

urlpatterns = [
    # /table/
    url(r'^$', views.display, name='display'),
]

Can somebody please tell me what is wrong?

Answer 1

You are referencing models.Book in your view, but you have not imported models . In your views.py you need to do from myapp import models . Or you can do from myapp.models import Book and change it in your view function to just Book.objects.all() .
